Peach tree `White Princess`

ABSTRACT

The present invention relates to a peach tree and more particularly to a new and distinct variety broadly characterized by a medium size, vigorous, hardy, productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the second week in August, with first picking on Aug. 10th, 1994. The fruit is uniformly large in size, excellent in flavor, attractively globose in shape, freestone in type, very firm and white flesh in texture and mostly red in skin color. The variety was developed as a first generation cross using the unnamed yellow flesh genetically dwarf peach seedling as the selected seed parent and `August Snow` (U.S. Plant Pat. No. 8,947) white flesh nectarine as the selected pollen parent.

BACKGROUND OF THE VARIETY

In a continuing effort to improve the quality of shipping fruits, we,the inventors, typically hybridize a large number of nectarine, peach,plum, apricot, and cherry seedlings each year. The present inventionrelates to a new and distinct variety of peach tree, which has beendenominated varietally as `White Princess`. The present variety washybridized in 1991 by us in a cultivated area of our experimentalorchard at Bradford Farms near Le Grand, Calif. in Merced County (SanJoaquin Valley). It was developed as a first generation cross using anunnamed yellow flesh genetically dwarf peach seedling as the selectedseed parent and `August Snow` (U.S. Plant Pat. No. 8,947) white fleshnectarine as the selected pollen parent. Subsequent to origination ofthe present variety of peach tree, we asexually reproduced it by buddingand grafting, and such reproduction of plant and fruit characteristicswere true to the original plant in all respects.

The fruit produced by the present variety exhibits the desirablecharacteristics common to its pollen parent, `August Snow` (U.S. PlantPat. No. 8,947) white flesh rectarine, by producing freestone fruit thatis white in flesh color, sweet sub-acid in flavor, firm in texture, andmostly red in skin color, but is distinguished therefrom and animprovement thereon by producing fruit that is larger in size, rounderin shape, and peach instead of nectarine.

The present variety is differs significantly from its selected seedparent by being genetically tall instead of dwarf and by producing fruitthat is white in flesh color rather than yellow, that is much firmer intexture, and that is sub-acid in flavor instead of acidic.

Although the new variety of peach tree possesses the describedcharacteristics under the ecological conditions at Le Grand, Calif., inthe central part of the San Joaquin Valley, it is to be expected thatvariations in these characteristics may occur when farmed in areas withdifferent climatic conditions, different soil types, and/or varyingcultural practices.

We claim:
 1. A new and distinct variety of peach tree, substantially asillustrated and described, which produces fruit that exhibits thedesirable characteristics common to its pollen parent. `August Snow`(U.S. Plant Pat.
